Polymerization process control system design
Abstract:With the development of science and technology and economics，the molecular polymet is of great use for every field．At the same time，high need to fulfill higher production quality requirements and autoimmunization of polymerization process．At present，the polymerization of polymer is largelyby batch chemical reactor,account for 90％Of all the parameters(such astemperature，pressure，flux，speed)to have influence on the polymerization production run，temperature is the most important parameter,deciding on thequaIity and output rate.Polyacrylonitrile as a product of the polymerization reaction,In life basically everyone used before.One of the important raw materials while also synthetic polyacrylonitrile,Has many excellent properties such as softness and warmth and good in the world, there are "artificial wool," said,But its strength is not high, wear and fatigue resistance is also poor, currently third in production after its polyester and nylon door.The design of the polymerization reaction, mainly through the power control software for drawing and testing completed.Synthesized by the polymerization of polypropylene, polyacrylonitrile by the reaction temperature control to achieve maximum yield of the reaction.
Keywords:polymerization；reactor；temperature control；The force control software
